I bought a sealed bag of LEGO bricks with no box or directions and I am trying to figure out which set it is. It is all grey, black, and clear pieces and looks to be 100-150 pieces. Any help is appreciated.
As I mentioned in my comment to OP's original question, this is an inner bag of a larger set, not a full set. It is a bit hard to tell which set it could be, as the pieces are too common to narrow it down from just one image. I did look up the 3x4 hinge-plate, as that was the most uncommon, but it still appears in 45 sets: https://www.bricklink.com/catalogItemIn.asp?P=44570&colorID=86&in=A
Upon more careful inspection, and narrowing down the pieces even further, it appears that this is the gray/black bag from the #10702 LEGO Classic Creative Building set: https://www.bricklink.com/v2/catalog/catalogitem.page?S=10702-1#T=S&O=
I came to this conclusion by verifying some of the other pieces in the set from the BrickLink Catalog, and also noticing that the 23mm D. x 7mm Offset Tread Black Tire only appears in the above mentioned LEGO Classic set from the list of 45 sets with the 3x4 hinge-plate.
